A woman in Utah got an unexpected surprise when she bought a box of tampons from a local store; the box was filled with cocaine.

Cindy Davidson noticed that a local store, NPS, was having a sale on tampons and decided that she better stock up, but revealed that the box did not look as if it had been tampered with.

That changed when she opened the box and noticed that something was not quite right with some of the packaged tampons.

"I noticed there was packaging inside that wasn't normal…They had removed the tampon and there was cocaine inside," Davidson told KSL.

When she first noticed that something was not right with the package she began to worry because there was a white powdery substance rolled up tightly in cellophane normally used to contain the cardboard applicator.

"I started getting nervous because I thought it might have been a terrorist attack," she said. "I called my sister first and said I was going to call the manufacturer the next day and she told me to call the police."

Salt Lake police detective Carlie Wiechman explained that when officers arrived at Davidson's home they could not immediately verify the powdery substance.

"They called in the hazmat team from Unified Fire Authority to have them test it, make sure that it was safe and that it wasn't something that could potentially hurt anybody handling it," Wiechman said.

Officials on scene tested the substance and the results revealed that it was powdered cocaine; they then told Davidson.

"I really couldn't wrap my head around it," she said. "I was just thinking it was crazy. I couldn't believe it had happened. It was just crazy to me."

The store where the drug filled tampons were bought took the remaining boxes off the shelves while local police were continuing their investigation as to how this happened and where the drugs came from.
